The Modules TR list existing practice as accepted by implementations.
I believe build systems that support modules already take care of differences.

There is no standard file extension for header files either, or C++ source files. It would be _more_ puzzling if we'd gone against the grain and standardized a file extension! Especially as the C++ standard doesn't require an implementation to even support "file extensions", as the naming of source files on a file system is out of scope for the C++ standard.
